    Abstract

    In the design of concrete structures, the modulus of elasticity, the modulus of rupture, and the split cylinder tensile strength of concrete are predicted from its compressive strength. In this paper, the relationship between compressive strength and other mechanical properties is studied for superplasticized concrete with W-C ratios of 0.28, 0.35, 0.45, and 0.55. Also in this study, the effect of different dosages of a high-molecular-weight sulfonated naphthalene condensate superplasticizer known as Lomar-D on the compressive strength, stress-strain relationship, modulus of elasticity, Poisson's ratio, modulus of rupture, and split cylinder tensile strength of normal, medium, and high-strength concrete mixes is investigated. Overall, 72 cylinders and 36 beams were tested in accordance with ASTM specifications. In addition, the effect of different dosages of the superplasticizer on the workability of different mixes and the slump loss with time was also measured.
